Cybersecurity Learning Roadmap.

Becoming a cybersecurity expert requires a combination of knowledge, skills, and experience in various domains of cybersecurity. Here are some key areas you should focus on to become a cybersecurity expert:

Networking Fundamentals: Understand the basics of networking protocols, devices, and concepts, including TCP/IP, DNS, routing, switching, and firewalls.

Operating Systems: Gain expertise in popular operating systems like Windows, Linux, and macOS. Learn about their security mechanisms, vulnerabilities, and hardening techniques.

Programming and Scripting: Develop proficiency in programming languages such as Python, C++, Java, or PowerShell. Scripting languages like Bash and PowerShell are also essential for automating tasks and security operations.

Cryptography: Learn the principles and algorithms of cryptography, including symmetric and asymmetric encryption, hashing, digital signatures, and cryptographic protocols.

Web Security: Understand web application architecture, common vulnerabilities like cross-site scripting (XSS) and SQL injection, secure coding practices, and techniques to secure web applications.

Network Security: Learn about network security concepts, protocols like SSL/TLS, virtual private networks (VPNs), intrusion detection and prevention systems (IDPS), and security technologies such as firewalls and intrusion prevention systems (IPS).

Malware Analysis: Gain knowledge of different types of malware, malware analysis techniques, behavior analysis, reverse engineering, and tools used in malware analysis.

Incident Response: Understand the processes and best practices for handling security incidents, including identifying, containing, analyzing, and recovering from security breaches.

Risk Management: Familiarize yourself with risk assessment methodologies, risk mitigation strategies, and compliance frameworks such as ISO 27001, NIST, and GDPR.

Ethical Hacking and Penetration Testing: Learn ethical hacking techniques, tools, and methodologies to identify vulnerabilities and perform penetration testing. This includes knowledge of reconnaissance, scanning, exploitation, and post-exploitation techniques.

Security Frameworks and Standards: Acquaint yourself with widely adopted security frameworks and standards such as NIST Cybersecurity Framework, CIS Controls, and OWASP Top Ten.

Security Governance and Compliance: Understand the principles of security governance, risk management frameworks, and compliance requirements. This includes knowledge of privacy laws, regulations, and industry-specific compliance standards.

Security Architecture and Design: Learn about secure network and system architecture, secure coding practices, secure software development lifecycle (SDLC), and secure cloud computing.

Cybersecurity Tools: Familiarize yourself with commonly used cybersecurity tools such as vulnerability scanners, network analyzers, SIEM (Security Information and Event Management) systems, antivirus software, and intrusion detection systems.

Continuous Learning: Stay updated with the latest trends, emerging threats, and advancements in the cybersecurity field. Participate in conferences, webinars, online courses, and join relevant communities to expand your knowledge and network.

It's important to note that cybersecurity is a vast and rapidly evolving field. Certifications like CompTIA Security+, Certified Ethical Hacker (CEH), and Certified Information Systems Security Professional (CISSP) can also provide a structured path to gaining expertise and enhancing your professional credentials. Practical hands-on experience through internships, capture-the-flag (CTF) competitions, or bug bounty programs can further solidify your skills.
